Its adsorption performance mainly depends on several main material parameters and process parameters on it [8. Material parameters including carbon adsorption porosity, thickness of honeycomb structure and the content of carbon; process parameters including fluid flow rate and concentration of the adsorption properties of adsorption, can adsorption depends on the carbon structure and adsorption properties of features such as molecular weight). The curve is one of the main performance characterization of adsorption, adsorption is the adsorbate concentration ratio before and after the change over time of a function [9 '. This ratio is 0.95, the amount of adsorption properties of adsorption is called penetration capacity. Penetration capacity depending on the fluid flow rate, the concentration of the adsorbate and honeycomb carbon component contentactivated carbon for gold recovery  Factors such as [10. For honeycomb activated carbon, the wall thickness is a very important parameter, by changing the wall thickness to improve its adsorption efficiency. Under the same porosity, thickness increases, the honeycomb carbon content per unit volume also will increase, which can improve the adsorption capacity. This is because the wall thickness increases, the fluid channel in the cellular cross-sectional area reduced, so the real surface or volume flow rate will increase. At the same time, the contact between adsorbate and carbon efficiency will, there is a balance between the two. Under the given conditions, the balance will determine adsorption increase or decrease. If the adsorbate at higherthe diffusion rate diffuses to the inside of the honeycomb wall, and the empty adsorption site can be continuously adsorbed, so the thick-walled honeycomb should have better adsorption efficiency and adsorption capacity"Determination of air velocity and cross-sectional area of empty towerThe empty tower gas velocity is the velocity of gas passing through the entire cross section of the adsorber.The selection of air velocity not only directly determines the size and pressure drop of the adsorber, but also affects the adsorption efficiency.activated carbon wholesale   If the gas speed is very small, the size of the adsorber is large and uneconomical. If the gas velocity is too large, the pressure drop will increase and the adsorption efficiency will be affected.The optimum gas velocity was determined by experiment.

The preparation methods of activated carbon include physical method, chemical method, microwave radiation method, etc.(1) Physical method. Physical method is to use carbon dioxide, water vapor or the mixture of both as activator, the carbonized carbon material and gas in the activation furnace at 500~1200℃ for carbon activation reaction, so that the pore size of the carbonized material to expand, the formation of activated carbon with porous microcrystalline structure.Gas activation method mainly includes carbonization and activation engineering.The so-called carbonization, refers to the low temperature (about 500℃) is small, the volatile coal tar molecules in the material and the thermal decomposition and curing process of asphalt, that is, to remove the volatile in advance, made suitable for the next step of activation with carbonization.activated carbon pellets wholesale  When the temperature is below 600℃, the specific surface area of carbonized material increases with the increase of temperature.When 600~900℃, the specific surface area reaches a certain value: 250~300 m2/g; when above1000℃, the specific surface area shrinks rapidly.china active carbon/   When the carbonization temperature is above 800℃, the reaction performance of carbonized compounds and activation gas gradually becomes weaker, so the carbonization temperature is generally below 1000℃. However, if the residual volatile content and thermal effect are taken into account, the most suitable temperature should be 600~700℃39]. The carbonized substance obtained from the carbonization process is placed in water vapor or a mixture of water vapor and combustion gas and heat treated at 800~1000℃, which is called the activation process.

Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics. activated carbon gold mining  Under experimental conditions, the gas-liquid mass transfer capacity of honeycomb ceramic catalytic reactor is slightly lower than that of ozone reactor, but when the gas-water ratio is greater than 0.15, the gas-liquid mass transfer capacity exceeds that of ozone reactor. The gas holdup (Eg) of ozone reactor and honeycomb ceramic catalytic oxidation reactor is 0.19% and 0.15% respectively when the gas volume is 0.L m3/h, indicating that the size of bubbles in the catalytic oxidation reactor is large, which is not conducive to gas-liquid mass transfer. The Pe values of ozone reactor and honeycomb ceramic catalytic reactor were 3.14 and 5.25, respectively, in the liquid pulse addition test, indicating that the liquid level pushing flow component in catalytic oxidation reactor is higher, which is conducive to gas-liquid mass transfer. The gas-liquid mass transfer efficiency of catalytic oxidation reactor is more affected by increasing gas-water ratio. activated carbon company
